vshaft 28 has an eccentric portion El() which tached the hammers/ier beaters 5. The

`beaters are preferably ivotally mounted on the supports 4, and `t erapid `rotation of shaft 2 causes hammbrs 5 to stand out ra dially under the influence Vot centrifugal force. A suitable-feed or hopper opening 6 is provided which communicates with the interior of the casing i. inthe sides 'of the casing 1 are provided 'arcuate slots 'i directed spirally toward the shaft 2. These slots' may. be machined directly in the casing Sides or they may bemachined in plates 8 set into the sides of the-casing. In the slots y are mounted transversely'extending rods 9, the' arrangement being such that as` the rods are moved longitudinally of the slots they 'are caused to spirally 'approach the allait 2.

At 'either side of the machine, as is best illustrated in Figs 2, hangers 10 are mounted on the rods 9, which hangers support o en.

flexible rings 11. "These rings are pre erably of elastic steel and are capable ,of considerable flexing. The substantially cylins drical screen or grinding'` cagev 12 is hung on the rings 11, attachment being by means of st-irrups 14 attached tothe screen 12 and embracing the rings 1l. The connection is such that a' certain sliding movement is per.-

mitted between rings l1 and the screen 12 when the diamcterof the rings is changed.

The upper ends of the rings are attached toYV a suit-able facer 15 which coperates .with a concave arcuate portion 16 olf vthe casing, having close Contact therewith. 'The other ends of the rings are attached to a suitable tie strip 17 which is capable of being moved toward and 'from the shaft 2 by means now to be describedl y The rear of the casing l just below the: feed opening 6 is formed with an aperture` 1 (see Figs. 3 and 4) having substantially vertical sides and substantially horizontal 'a sliding member 25 which .has ay bottom Wall 26 and side walls 27. An adjusting shaft 28 is journaled -in sliding bloc rs' 29 which are mounted in the casing l ,so as to Adjusting passes through enlarged openings 31. in the sid walls 22 and cooperates with suitable journals or bearings in sliding member 25;

Adjusting shaft 28 carries at its extremities crank arms 34, at the outer ends of which are 4attached adjusting links 35. Adjusting lare attached to crank arms 84, `extend 4either side of the casing 1 to they uppermostloo mesme shaft 28 vmay be rdtatedby a Vsuitable hanf' dle 36, such rotation/operatingto,move slidvf able member '25 inwardlyfor outwardly' 'bf casing 1, due vto theeccentric ortion of shaft 28 coperating with sli ing mem-1e ber 25. v

A shifting shaft 37 is journalcd in sliding: blocks. 38 mounted to slide vertically in the sidewalls 22 of adjusting member 18. This shaiftalso has an eccentric portion 39 op-` 75 erating `in 'suitable j ournals` or bearings an sliding member 2 5; This shaft may beirotated by a handle-10, and' when so rotated 1 operates to shift adjustable member 1'8. in-

wardly or ontwardlyupon sliding member g@ 25. During such. movement off adjustable member 1S, sliding member 2,5 is held sta'- tionary by shaft 2 Tie strip 17 '1s attached to the bottom wally of sliding 4member 25,- and v upon inward 35 movement of sliding'member 25 islmoved j toward shaft 2, thereby bringing the lower extremity of screen 12 closer vto theoperctf ing-extremities of hammers 5. This inward movement of tie strip l17 also-exerts com- 90 pression stresses upon rings 11, 4which' .stresses are communicated-to rods 9, tendsI ing to move them in 'slotsf' lspirally toward shaft 4 2. It will be remembered that this inward movement of tie strip 17 isaccom- '95 plished by rotation of adjusting shaft 28, and this rotation of adjusting shaft 28 also swings crankarms 34. vThe Vlinks 35, which on rod 92 to which are attached the hangers 10 nearest the upper extremity of the screen 12.

The swinglng of crank arms 31h draws upon links which tends to Apull the uppermost rod 9 in its slots 7 'spirally toward the 105- shat 2v and transmits tension stresses to rings 11, which tension stressesf operate in the same direction as-do the compression stresses occasioned by inward adjustment of v tie strap 17. The 'resultlis that the .extremi` 110 ties o rings 11 arefbrrmght closer together and the diameter of the rings decreased.

This movement'of rings llca'uses a similar contraction or the'gscreen 12, relative circumferential Inoveirient-v vp 'ungs 11 and 1-15 screen 12 being permitted bystirrups 14` as above"described.Y The p'o'sitionand inclina? tion of various yslots 7 iis -su`ch` that durin this contracting movement of -rings `11; an screen `12,'fthey are 1inaintaimedy concentric "ibo with shaft 2. This insures all"'ponts on; Vthe grindin suraceyofscreen 12 being ad" e same"extentl 1 radially; o fthe shaft,and thereby nsures'ujniferm coperf "L: ation between the ends fopfgtheliammers'and 125 justed to Yt 1li/c, grinding cage.. j 'Coincide ntK @with these movements of i rings '11 adjustable member 18 will also be movedtowardshaiit2'to 'an equal extent by virtue ofthe engagement'beg tween adjustable member; 181- and sliding -1,30

member 25 through shaft- 37. However, breaker plate 2l may be adjusted independently of movemento adjusting shaft 28 by operation of shaft 37 as above described which moves adjustable member 18 relative to slidin member 25 While .sliding member 25 is hel stationary in the frame.

Suitable space is afforded between the facing plate 15 and the casingvof the Jfeed opening 6 to allow for the contraction of rings 11, and the engagement of facing plate 15 with the arcuate portion 16 ofthe cas-A ing prevents material from being thrown out of the grinding cage if the adjustment is made while the machine is in operation. When the parts are ,adjusted to proper positions, they may be secured therein by the screws 4l and 42 which lock shafts 37 and 28 against rotation. j

By virtue of this construction, it will be obvious that as the grinding cage is adjusted its diameter and its degreeof curvature is changed. Thereby the cage is always maintained concentric with the shaft, and this insures a uniform cooperation between the hammers andthe cage throughout the extent of the cage.
